Just click OK until it’s all done with the install process. Wait for SDK Manager to download install and all the packages, and don’t panic if it asks you for permission to kill a server or process. You’ll need this file to let your PC communicate with the Kindle Fire. Go ahead and install all the prechecked packages, but make sure that the Google USB Driver package (listed under Extras) is checked. Once the Android SDK is finished installing, the SDK Manager app will automatically open with a list of software packages you can download. Simply open installer_r15-windows.exe and follow the instructions. All you need to do is to open the installer file you downloaded (mine was called jdk-7u1-windows-i586.exe) and click through the installer wizard. Make sure you do this before you install the Android SDK. Step 4: Install the Java Development Kit. Make sure to download the appropriate version of the Java Development Kit for your PC–I’m on a 32-bit Windows 7 PC, so I downloaded the Windows x86 version. Step 3: Download the Java Development Kit (version 7, at the time of this writing).
